In this tutorial, I'm going to show you a way to prepare a scene for your cars. I made this car by myself without the help of any blue prints. This tutorial is not about creating the car so I wont be explaining how I modelled it. But you can see some steps in the animation below.

I modelled the mustang using some reference photos which shows off all the details of car partly as you can see in the picture below.

I've chosen to use "Raytrace" for creating the car's paint texture as you can see below, The properties that I used for the cars paint are below.
